4. General Information Oyster Creek is a non-ARTS plant. There are Oyster Creek specific flow-biased and power-biased MCPR operating limitsfor operation at less than rated flow and power. The flow-biased MCPR limits are discussed in Section 6.1. The power-biased MCPR limits are discussed in Section 6.2. Section 7 provides power-biased LHGR limits for PROOS operating condition and flow-biased LHGR limits for operation with one TBVOOS. Rated core flow is 61 Mlb/hr and operation up to110.7% of rated is licensed for this cycle. Additionally, Oyster Creek utilizes an ELLLA operating domain, which hasexpanded the power/flow map to allow for greater operational flexibility.

Average Planar Linear Heat Generation RateThe MAPLHGR limits are discussed in Technical Specifications Section 3.10.A. The MAPLHGR limits for the lattices ineach fuel type as a function of average planar exposure are given in Tables 5-1 through 5-22 for operation with zeroISOLATED RECIRCULATION LOOPS (Reference 2). For operation with one ISOLATED RECIRCULATION LOOP,multiply the limits in Tables 5-1 through 5-22 by the ISOLATED Loop multiplier listed in Table 5-23 (Reference 2).

6. Minimum Critical Power RatioThe MCPR limits are discussed in Technical Specifications Section 3.10.C. For all conditions, the more limiting of the flowadjusted MCPR and power adjusted MCPR is applied.6.1. Manual Flow Control MCPR LimitsThe flow adjusted MCPR is determined by multiplying the applicable rated condition MCPR limit shown in Table6-1 by the applicable MCPR multiplier, Kf, given in Table 6-2. Table 6-1 MCPR limits are the maximum valuesobtained from analysis of pressurization and non-pressurization events. MCPR values are determined by thecycle-specific fuel reload analyses in Reference 2 and in Reference

15. Table 6-1 MCPR limits are bounding forboth GEl 1 and GNF2 fuel. The Kf multipliers are documented in Reference 2 and Reference

15. Table 6-1 limitsare independent of APRM status changes since Reference 2 and Reference 15 analyzes the Rod Withdrawal Error (RWE) as unblocked.

The appropriate Kf value may be determined by linear interpolation. Table 6-2 isapplicable to GEl 1 and GNF2 fuel types per Reference 2 and Reference 15.Table 6-1 provides two sets of MCPR limits. One set is for "Nominal" response function for the Turbine BypassValve (TBV) where the TBV fast opening to 80% of rated TBV flow has been demonstrated to be 1 second or lessand has a TBV fast opening delay time of 200 msec or less (Reference 14). The other set, referred to as "Slow toOpen", represents MCPR limits which have taken no credit for the fast opening function of the TBV during aFeedwater Controller Failure (FWCF) event. The application of the ("Nominal" versus "Slow to Open") MCPRlimits is dependent on the results of TBV testing. Operation with one TBVOOS is independent of the TBV fastopening response time since the 1 TBVOOS MCPR limits in Table 6-1 take no credit for TBV response(References 2 and 15).6.2. Power Dependent MCPR LimitsThe use of GNF2 fuel type requires the application of power dependent MCPR limits at off-rated conditions. Power dependent limits are required because APRM Trip Setdown may not provide adequate protection for theMCPR Safety Limit. Use of these limits ensures that the MCPR Safety Limit is not violated as a result of anyanticipated operational occurrence (AOO). Plant specific power dependent MCPR limits are presented in Table6-3 and documented in Reference 2 and Reference

15. When core thermal power is greater than or equal to40% of rated, the Kp multiplier from Table 6-3 is applied to the applicable rated condition MCPR limit shown inTables 6-1. The appropriate MCPRp or Kp value may be determined by linear interpolation.

Below 40% of ratedpower, the MCPR limits in Table 6-3 are applied directly. Table 6-3 is applicable to both GEl 1 and GNF2 fueltypes per Reference 2 and Reference 15.Table 6-3 provides two sets power dependent MCPR limits at off-rated conditions. One set is for "Nominal" response function for the Turbine Bypass Valve (TBV) where the TBV fast opening to 80% of rated TBV flow hasbeen demonstrated to be 1 second or less and has a TBV fast opening delay time of 200 msec or less (Reference 14). The other set, referred to as "Slow to Open", represents power dependent MCPR limits which have taken nocredit for the fast opening function of the TBV during a Feedwater Controller Failure (FWCF) event. Theapplication of the ("Nominal" versus "Slow to Open") power dependent MCPR limits is dependent on the results ofTBV testing. Operation with one TBVOOS is independent of the TBV fast opening response time since the 1TBVOOS MCPR limits in Table 6-3 take no credit for TBV response (References 2 and 15).6.3. Scram TimeCore average scram insertion times are determined per Technical Specifications 3.2.B. Based on the results ofthe scram time surveillance testing and calculation of the core average insertion time, a MCPR limit is chosenfrom Table 6-1 (Reference 2 and Reference 15). If the core average scram insertion time does not meet theOption B criteria, but has met Option A criteria, then the appropriate MCPR value may be determined from alinear interpolation between the Option A and B limits with standard mathematical rounding to two decimal places.The scram time adjustment to MCPR only applies to MCPR limits that are set by pressurization transients (seeNote 3 to Table 6-1 for further clarification).

' The documented MCPR limit is based on the Rod Withdrawal Error (RWE) event, which is a non-pressurization event. The limitingpressurization event results in an Option B MCPR limit that is 0.01 less (BOC to (EOR-4016) MWD/ST) than the RWE event. Scramtime adjustments are only required to be applied to MCPR limits that are set by pressurization transients. 4 For three recirculation loops in service, the MCPR operating limit is 0.02 greater than the four/five loop value per Reference 2.' 1TBVOOS MCPR limits are independent of TBV response function because no credit is taken for the TBV response function.

01. Introduction and SummaryThis report, which supplements the Supplemental Reload Licensing Report, contains thermal-mechanical linear heat generation rate (LHGR) limits for the GNF-A fuel designs to be loaded into Oyster Creek forCycle 24. These LHGR limits are obtained from thermal-mechanical considerations only. ApprovedGNF-A calculation models documented in Reference 1 were used in performing this analysis.

LHGR limits as a function of exposure for each bundle of the core design are given in Appendix A. TheLHGR values provided in Appendix A provide upper and lower exposure dependent LHGR boundaries which envelope the actual gadolinia dependent LHGR limits. The LHGRs reported have been rounded totwo places past the decimal.Appendix B contains a description of the fuel bundles. Table B-I contains a summary of bundle-specific information, and the figures provide the enrichment distribution and gadolinium distribution for the fuelbundles included in this appendix. These bundles have been approved for use under the fuel licensing acceptance criteria of Reference 1.Page 3Page 29 of 59 Exelon Nuclear -Nuclear FuelsCore Operating Limits Report For Oyster Creek 1 Cycle 24Non-Proprietary Information Submitted in Accordance with 1 OCFR2.390 Oyster Creek Non- Proprietary Information Reload 24 Class I (Public)COLR Oyster Creek 1 Rev. 90000-01 38-9259-FBIR-NP Revision
